• FPGA DMA not found in bitfile

  Hi all

  I ran into a strange and frustrating problem.  I have a project enough throughout the development process that contains a target FPGA on the cRIO 9081.  I've been transfer of large amounts of data through a target to host DMA FIFO.  I changed the number of items in the FIFO of 512 to 8 k > and all of a sudden the FIFO is longer when the FPGA reference is configured with the synthesized bitfile.  The FIFO is visible when I configure with the option of VI, but when I run the VI on the host and you try to start the buffer, I get the error-61071 with the explanation "LabVIEW FPGA: FIFO DMA selected could not be found or is out of sync with the bitfile.»  I tried to change the size of the buffer, renaming and recompiling, but I get the same result (which is incredibly frustrating, because the compilation process takes about 30 minutes each time).  I'm to the point where I have to try to rebuild the project, but this seems to be a terrible solution because I have to rebuild many of the options of the target.  We never seen anything like this?  Am I missing something?    Someone at - it ideas?

  Cheers, Matt

  My best guess is that '999' is always bigger than "500" (constant), so the false case of the structure of your business can never be reached, so the compiler optimizes out. If you place one of these constants to a control, you can test my theory.

• FPGA (DMA CONFIGURATION)

  Hello

  IAM pumping in data series (RS-422) AT BAUD RATE (4800bps to 38400 bps) to different channels. IAM using flex rio (7965 R) WITH adapter FLEX RIO (NI 6584). I wanted to know what should be the configuration of dma (target to host) which is the number of items and the data type (side fpga) asked

  And also what requested various items means? What is bytes or kilobytes?

  Concerning

  YOUSSEF

  Number of items requested is bytes or kilobytes. This is the number of items and the number of bytes will be based on the data type you choose. So, if your dma holds I32s and you choose 8 elements, it will be 32 bytes. Knowing this, you should be able to determine how many items you need. It also depends on the RT controller you have. The faster you can remove components of the FIFO, the number fewer items to keep.

• FPGA: error message - Item not supported

  Dear all,

  I am a new user of Labview. I try to use OR 7855R. FPGA Module is installed on the computer, but when I try to run sample files, I get an error message that FPGA plugin is not installed or there is an expired license. But FPGA module is installed, two times to make sure that is not the problem, and I also have a license for the development of FPGA too.

  Do you have an idea how to fix this? I'm stuck here for almost 10 days now!

  Thanks in advance!

  It's true. You should have received a disc or two for this with your copy of LabVIEW, if you have bought this module. It also appears you can download from http://www.ni.com/download/labview-fpga-module-2014/4827/en/ , but note that this is a large installation (I have not downloaded this file, I just know it's a great Installer off the discs).

• FPGA graphic wavefrom does not

  Compact rio using a fpga. 9014/9114

  In a project of interface fpga if I create table and then plug it directly into a waveform chart it says that the table must be of fixed size.

  However, I tested using a constant arrary of fixed size, initialize arrary to size fixed... etc, but it always happens with this error when you try to run the VI.

  I have autopreallocate tables and strings as stated in the help file, but still it comes up with the error.

  LabVIEW 11, sp1 (completely up to date)

  I am running as a 'run on the development computer.

  The arrary is fixed point type 27 bits wide (fft output)

  First of all, in your code, you use a graphicof the waveform, not a graphic waveform as what you wrote in your messages before!

  Then DBL is currently a data type not supported on the platform FPGA LV. There is also a strange problem with graphics on their type has spread to the FXP data type.

  So the question I have, is that if you place a waveform graph or a chart in the palette, it is DBL. If you then connect an array of FXP, you get the error message you see since the graph or table does not spread to the FXP data type. If you change the data type of the table for example I32, the type of charts or tables becomes I32. If you redefine the I32 with FXP then, everything works as it should.

  This means for you, first create a table of I32 and connectivity for the chart or table to get rid of the wrong size fixed. Then change the table in FXP.

  I just need to do some more research on this problem and will post backs.

• PCIe-7842R (series R FPGA) digital output does not work properly

  Greetings,

  I'm having some problem show TTL the correct voltage with my PCIe-7842R FPGA board.

  The block diagram of my code FPGA LV Moose appears in "analog - digital .png '. The idea was to convert an analog input (decimal value) to a binary code and 16-bit output by 16 DIO ports. I use the connection block SCB-68 has as the terminal and trendy on the FPGA 1 connector RDIO with SHC68-68-RDIO shielded cable.

  The compiled code ok. But during the test, I noticed that some ports has no output TTL levels correctly. For example, for input 1000 decimal, I would expect binary code 0000001111101000. However, some ports (DIO #6, #7, #9, etc.), which are supposed to ~3.3V (1 digital) high TTL output, output actually 0.8V. I have attached the result measured in 'exit digital test.png '.

  To ensure that the question was not because of the code of the LV, I did some more tests on DIO #6 with a simple example (simple digital output.png). The output was ~ 1V this time at the digital 1.

  It's really confusing because of the digital Edition is supposed to be simple. I used the same FPGA card for controlling roller shutters with TTL signals before and it worked fine.

  Does anyone have similar problems? Any suggestions are greatly appreciated.

  DIOs are connected to a controller digital galvo Cambridge Tech. But I measured the voltage at the terminals of the connector block.

  If you unplug the controller galvo DIOs, do they look good (have the right voltages).  Do you know how many of these entries to the need for controller?  I think you hit the limit the total current available for EID within the Council.

• FPGA - DMA with several cMoudules

  Hello!

  I have a Setup with a cRIO (cRIO-9114 chassis, controller cRIO-9025) and four cModules, NI 9225, NI 9227, NI 9232 and NI 9239. The 9232 NOR has a max of 102,400 kS/s sampling rate, while the other three have 50 kech. / s.

  I use DMA FIFO to transfer the data from the FPGA and there are only three DMA channels. Since the 9232 NOR has a sample rate most high, I used a DMA FIFO transfer data for this add-on. But for the rest cModules, I want to transfer data from each of them in some cases while in others, I am only interested in the data of one of them. It is advisable to transfer all of them in a FIFO DMA? Is it possible to use a FIFO DMA to transfer data for all four cModules?

  Thank you!

  If you transfer a lot of data for the code in real time, you must make sure, you can manage the treatment of it, which will be a lot of data to receive, process, store/transmission etc.

  But in any case, it is certainly a good idea to use a DMA for data 9232. For the three other modules, if you are only interested in a number of modules whenever you read from them, then you must implement a policy for the reception of data through a second DMA channel.

  A solution might be to precede the data with a unique value, also sent through secondary DMA, which defines the incoming data. For example, you can use a condensed binary byte (upconvertis to any type of data do you cross the DMA), in which the first three bits declare what modules are actively playing. So for 00000111 you read from all of the modules, with 00000101 you read modules 1 and 3. The amount of data after this condensed binary byte will depend entirely on the modules that you are reading from, clearly the maximum number allowed will be for the three modules, but in all cases, you can go out and prepare to receive the end of RealTime data properly.

  It's just a suggestion. There are better options, include leaders from Pack and terminators, in which case precede you the binary byte condensed with a known value to provide guarantees that the DMA buffer is always synchronized, but these concepts are difficult to describe in a single thread post...

• Target visible FPGA in MAX but not in LabVIEW

  Hey!

  I recently installed a RIO device. Before installing the equipment, I installed the module FPGA & RIO 3.0 as directed. Now, I can see the device in a position & automation explorer, but its not in list "Add target & devices. It says "No device found" in the existing devices tab. I don't understand the problem. :/

  Add the target under 'my computer '.

• DMA 2100 will not connect, 'seen' by Vista media center, but disconnects...

  You just bought a DMA 2100. But I can't seem to connect propperly. It's what I've done and the results...

  1A tried to connect via the wireless network. Seamed to work properly, until the last step when you are 'twinning' it to the pc of the VMC. (Vista home premium). VMC has stated that he is not able to connect to the Extender, even if afterwards it says "Ready to use" under the Linksys in VMC image. Result when I went to my TV, the DMA 2100 said he had lost the connection. Tried the buttun to reconnect, but it disconnected immediately.

  2 tried the same thing on wiered ethernet. This time, VMC could connect, and everything that was going on well, until I went back to my TV and then the DMA 2100 connected for about 2 seconds (I could just see the Media Center GUI for a second), input disconnected...

  3 tried to uninstall Arcsoft Media Theather (plugin for VMC) on the host pc. This time when I went back to television, the DMA 2100 connected for 5 seconds approximately. This time I even managed to use the remote control to scroll through the GUI, go up and down several times before it disconnected again...

  I installed the letest firmware, installed the instalation DVD of linksys and disabeled the firewall...

  Anyone have any ideas?

  Var guilty ASUS ACPI CENTER which was runnning in the background...

  Go to TASK SCHEDULER, and then expand the tab on the left. Select ASUS "folder", and then clear the two files (Asus ACPI Center and "Asus Regsomething, don't remember exactly name...)

  Reboot, Ant, and then it works fine!

• Virgo timeout, delaydeployer not started

  I'm trying to start the blank server to deploy some examples of applications modified.  However lately the Virgo runtime does not start and expires after 300 seconds.  I checked the deploy.timeout configuration variable, and it is 0 to disable expirations.

  Whenever I run Virgo, it gets stuck from the vmware tool delaydeployer.  Any ideas?

  newspapers, the delaydeployer starts, but never started, then Virgo is to expire.

• IR + jQuery + effect of waiting - not showing not the region setting

  Hi all:
  
  I have two problems 1) implementation of a hint of Martin Giffy D'Souza does not feature with IR + jQuery work and showing an effect of waiting prevent users to run the IR again. I add the parameter of a region to pass variables to the IR.

  There are several ways to do so, but an easy one would be to add an onClick event on your submit button that uses the same code

  onClick = "goModal ('apexir_LOADER', {position:['30%',]});}).

• FPGA read/write does not not in cRIO-9073

  Hello.

  I'm stuck with a problem in the use of the FPGA Read/Write control please suggest a solution.

  I use cRIO 9073 and I'm trying to place an order ON / OFF of GUI-> RT-> FPGA host. I use a shared variable of the network to transmit the control GUI form to host RT and I use read/write control to FPGA. I also put a Boolean flag in the FPGA VI to control if the control is transferred to the FPGA.

  When I toggle the button in the GUI, I see the same change in the host of RT (shown as 16 probe in attachment 1). However the FPGA indicator (indicated as probe 19) remains the default false state. The FPGA VI is on attachment 2.

  Thank you

  Guilhem

  Your FPGA only reads the control once before entering the loop.  If you want to read control permanently, you must put it inside the loop.

• FPGA: 'the bitfile signature does not match." Any changes made

  Hello

  I have a project involving a cRIO9082 and its FPGA target. My problem is that I keep having to recompile the FPGA build, even when I have not changed anything. Is there a setting I'm missing here?

  Thank you

  Ok. It is difficult to say why his need to recompile, but the quick fix is here: Configure open the VI FPGA to open bitfile, not the VI (you will need to create specifications to build on FPGA, integrate the bitfile VI).

  With regard to the reasons why he needs to recompile every time:

  -Are you moving this code between different machines (via control code source for example)? Different version (SP) of the LV or FPGA module may be the reason.

  -Make changes in the subVIs of your FPGA VI main?

  -Do you have screws that serve both on FPGA and RT?
